How to use Facts Manager node

Facts Manager node is created especially for Engage. But based on your business use cases, you can use this node to fetch the questions, related topics, facts, and so on.

For example, in a K-Graph named “FAQ - Fact mngr“, we have created Facts with the Topic "Voice Search" and the Relationships “Description”, “Benefit“, “Optimization“, ”Implementation” in it.

If you want to know all the relationships associated with the topic Voice search, you can use the Fact Manager node and get the result.

Sample Experience Designer flow

  1. Set the topic using the function node that feeds to the Facts Manager node.
    Sample code for the function node:

    var _ = global.get('lodash'); _.set(msg, 'payload.orbita.facts.topic',"Voice search") return msg;

  2. Select the K-Graph and select Relationships from the populate field in the Facts Manager node.

  3. You will get the list of all the Relationships associated with the topic Voice search in the debug tab at
    msg.payload.hub.relationships

Troubleshoot

If you did not select the Knowledge Graph in step 2, you will get the error “Mandatory field kgraphId is missing“ on the Facts Manager node in the Experience Designer. (Refer to screenshot below for the error message.)
